The reason for the overwhelming Israeli kills was due to the fact that the Israelis were using a fire control system that allows the Pilot to target the enemy through his helmet visor and fire missiles that are able to engage from the left, right up down.
The Americans were using their HUDs and Sparrows.
...if I am not mistaken.
And by the way the Python had been offered to the states, however it was denied (i don't know whether it was by brass or by congress....although i would put my money on congress). It would have been a welcome addition to our arsenal since the no.2 is Russian (the R-73) and is in use in some other nations.
However, Python missile and Helmet slaved firecontrol or not, a ratio of 220 out of 240 for the Israelis is still shocking when you consider the 'foe' was American F-18s!
If somebody else has better stuff, then we need to get it, analyze it, and improve and innovate !
If the Confederates had been equipped with rifled arms and repeating weapons , etc the outcome would have been different. So the Israelis know that valor can't make up for out-of-date or ineffective weapons . (Also remember Polish calvary vs. Nazi tanks.)
